DBSM R2023 - Individual building footprints for EU27 from the hierarchical conflation of OSM, Microsoft Buildings and ESM R2020

This vector dataset contains information about individual building footprints covering all countries of the European Union (EU27). This is the result of conflating the building footprint polygons available in three datasets, and in the following order of priority: OpenStreetMap, Microsoft GlobalML Building Footprints and European Settlement Map.

Results indicate how DBSM R2023 compares robustly agains cadastral data from Estonia, used as reference area.

The comparison with GHS-BUILT-S, reveals a relative overestimation of the latter, factored by 0.68 at the EU scale for a sound match.
While this dataset only contains the polygon of the building footprint, the aim is to continue to add relevant attributes from the point of view of energy efficiency and energy consumption in building in future versions.
